Gareth McAuley and Jonas Olsson have signed new West Brom deals.
The experienced international pair, who were out of contract in the summer, have been given new one-year deals.
McAuley said: “When you're settled somewhere and you are enjoying your football then it's an easy decision to make."
Swedish international Olsson, 33, said: “Both of us have been here for a long time but I think we agree that the dressing room we have here is something special."
